# Express 18 kW in Ampere [Complete Calculations with Chart for Different Voltage Levels]

18 kW or 18 kilowatts can be expressed in amps or amperes for the known value of voltages using kW to Amps formula calculator.

## 18 kW to Amps Formulas

The calculation formula for expressing 18 kW in amps are shown below.

Let’s take a look at the formulas:

## Chart for 18 kW to Amps expression

The power factor is assumed 0.8 in case of AC circuits.

## Solved Examples for 18 kW to Amps for DC and AC Circuits

### In the case of DC

A 120 V DC volts applied across a circuit consuming 18 kW of power will have how much current flowing across it.

Solution: Using formula

I = (kW * 1000)/E = 18 * 1000 / 120 = 150.

### In case of Single Phase AC

Repeat the previous problem for single-phase AC circuit assuming power factor to be 0.8

I = (kW * 1000)/(E*PF) = (18 * 1000) / (120 * 0.8) = 187.5 A

## In case of Three Phase AC

Repeat the problem for three-phase AC while assuming Power factor as 0.8

I = (kW * 1000) / (E*PF * 1.73) = (18 * 1000) / (120 * 0.8 * 1.73) = 108.38 A
